Windows 7: Computer stuttering in Windows 7 - Reformatting doesn't help

My computer was stuttering badly recently. It runs smoothly in games like FIFA 12 initially, but after a period of time (could be 5 minutes or an hour), the game starts to stutter. FPS doesn't really drop but the game stutters so badly I couldn't even play it. As I exit and try to load Skyrim, the initial loading might take up to 5 minutes, which is incredulous even when loading the world map.

That aside, Firefox was also stuttering whenever I tried to scroll, be it a page full of graphics, a text file or pdf.

All these problems could be 'reset' by restarting my computer but the symptoms just come back soon after.

Thought I might have too many programs installed, so I decided to reformat my computer and reinstall a clean copy of Windows 7 Ultimate x64. Didn't really help though. After installing all my drivers, the problems persist.

I am currently using AVG as anti-virus and didn't detect any rootkit virus or anything.

My CPU temperatures are fairly normal for Core 2 Duo E6600, doesn't go past 60C in the tropics. The CPU loads <10% when idle and max out when playing games. Same goes for GPU. None of them are overclocked. The problems only happen in the past month or so. Encountered no such problem previously, therefore I suspect it could be fault on the hardware part.

Any help would be greatly appreciated :)

60c is like the max temperature for that processor, it might be throttling down to prevent damage, try cleanning the heatink leaving it dust free and apply a fresh coat of thermal insulation material like artic silver 5.

If you haven't already, check out your network devices/settings. I suffered with PC stuttering from new for about 18 months (drove me to distraction).

Long story short: I swapped my PCI network card for a simple and powerful USB dongle (TP-LINK), using no additional software. It cleared it up in a flash.

This problem was probably the most irritating I've ever encountered.

AVG is bloated crapware no one here recommends for years. Replace with Microsoft Security Essentials
and only the Win7 firewall.

Test your RAM - Test with Memtest86+ for 5-6 passes or overnight to stress it. Test sticks and slots, swap sticks, checking for debris in slots.

Then as necessary work through these other Troubleshooting Steps for Windows 7
